MiniVibe includes a custom, hardware-independent 10-band Biquad IIR DSP pipeline that operates directly on 16-bit PCM audio streams.
Features 10 adjustable frequency bands (31Hz, 62Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz, 16kHz) with low-pass and high-pass shelving filters. Custom gain adjustments range from -12 dB to +12 dB.
Low-frequency resonant shelving algorithm enhances low-end punch without distorting midrange vocals or introducing muddy artifacts.
Midband peak filtering (1 kHz to 3 kHz) highlights vocal presence and spoken word clarity in acoustic and live recordings.
Simulates natural room acoustic reflections using comb and all-pass delay filters to add spatial depth to headphone listening.
Enforces a hard -1.0 dBFS ceiling across all audio output streams, preventing digital clipping and harmonic distortion at high gain settings.
Dual ExoPlayer buffer swapping guarantees zero silence between continuous album tracks and customizable 1s–10s crossfading.
